A goalkeeper, speaking on condition of anonymity, told The Sun: “It is more like a volleyball and it moves in the air so much. The Nike one was not like that.
"I don’t ever remember a ball like this and I have got one at home to keep getting used to the feel of it.
“It is extremely slippery which makes it difficult to handle. There will be a lot of mistakes this season.
“The ball has apparently been made for strikers but they also struggle with it because of the movement.”
Another goalkeeper anonymously claimed the new ball is "horrible" and would limit the number of catches stoppers attempted.
